Glycolysis: Study Guide SparkNotes

WebNational Center for Biotechnology Information The enzymes that catalyse glycolysis are regulated via a range of biological mechanisms in order to control overall flux though the pathway. This is vital for both homeostatsis in a static environment, and metabolic adaptation to a changing environment or need. The details of regulation for some enzymes are highly conserved between species, whereas others vary widely. how many teams did kyrie play for
